Product Overview

Corner Tube Boiler

Corner Tube Boiler refers to the boiler supported by angle pipes (large-diameter downcomers) set at its four corners, with the drum arranged horizontally at the top of the boiler front wall, and the whole is a full membrane wall structure, which means a closed water-cooled structure is formed around the boiler body, and all the heating surfaces are supported by themselves. The heating surfaces are able to expand freely, simplifying the boiler structure and saving steel. The furnace wall of the boiler adopts light membrane wall, which has less heat storage and can make the boiler cool quickly in case of accidental power failure, making the boiler safer.

Technical Advantages

Unique Structural Design

1. High boiler thermal efficiency
The membrane water wall of the boiler adopts fully welded structure, which has good sealing and no air leakage, reduces the excess air coefficient of flue gas and reduces the loss q2 of flue gas; The heavy refractory brick and red brick wall structure used in traditional industrial boilers is changed into light furnace wall, which has good heat preservation effect, heat dissipation loss q6 reduction, small heat storage of furnace wall and rapid start and stop of boiler.

2. Light steel consumption-no steel frame structure Corner Tube Boiler adopts a self-supporting structure, the weight of the body is supported by the membrane water-cooled wall and the downcomer, and all the membrane walls are welded into one, which has good anti-vibration performance.

3. New furnace wall insulation, low cost of boiler room The outer wall of the boiler uses light insulation material, and the outer cover is model slab, which has good heat insulation effect. There is no brick in the inner and outer wall of the boiler, and its no steel frame structure can greatly reduce the weight of the boiler. The total weight of the angle tube furnace is equivalent to 1/2 of the same type of bulk boiler. The bearing capacity of the boiler foundation is reduced by more than half, and the body height is also reduced. The height of the whole boiler room can save a lot of building materials, which greatly reduces the total cost of the boiler room.

4. Compact structure, nice appearance and little pollution The whole boiler is like a large container, with plastic sprayed steel plate or galvanized corrugated plate on the outside, and the color of plastic sprayed plate can be selected by the user. The boiler has high thermal efficiency and less chemical incomplete combustion loss. Due to the low flow rate of flue gas at the tail, it plays a role in soot deposition. All sides of the boiler body are welded by membrane wall, which is fully sealed by steel structure, preventing the occurrence of air leakage, and greatly improving the hygiene and cleanliness of the boiler room.

5. Superior performance and safety There is no refractory brick wall in the furnace of corner tube boiler, which is heated evenly. The membrane water-cooled wall produced by international standard, which has small thermal stress and fast heat transfer. Therefore, this type of boiler has rapid start-up, rapid temperature rise and strong adaptability to load change. There is no refractory brick wall structure in the furnace, which reduces a large amount of heat storage. The grate frame is reasonably designed, especially the cast iron structure is used in front of the frame supporting the driving shaft, which effectively ensures that the driving shaft will not shift locally under various loads. The whole boiler is welded together by the membrane water-cooled wall, and the ball which can be freely shifted is installed at a certain angle at the pivot point on one side of the boiler, which can avoid the damage of thermal stress caused by the thermal expansion and contraction of the boiler.

6. Low failure rate, easy maintenance and long service life Corner tube boiler is easy to maintain and the furnace grate is easy to assemble and disassemble. If the furnace grate is damaged in the boiler operation, it can be replaced at will without stopping the furnace. The membrane wall can be patched, and several rows of tubes need to be cut off every time the convection tube bundle of the two drums of the bulk furnace is replaced. Corner tube boiler is lower than the traditional bulk boiler and has a relatively compact structure, which completely eliminates the corrosion of furnace components caused by low-temperature condensation of corrosive volatiles in the upper part of the blast furnace chamber.

7. Low installation, operation and maintenance costs The boiler is shipped in large pieces and assembled on site, which can shorten the installation cycle of the boiler and save the installation cost. The boiler has high thermal efficiency and easy operation, which greatly reduces the labor and electricity cost. As the boiler has no refractory brick wall, it can save a lot of boiler maintenance cost every year.

Innovative Design

1. Turbulent design of secondary air The main role of the secondary air is to disturb the airflow in the furnace and enhance mutual cooperation, so as to reduce the q3 and q4 heat loss without increasing the α. The use of the counter blowing of secondary air, can organize the vortex flow of flue gas, can extend the travel of fly ash in the furnace chamber, and can make part of the fly ash fall back to the grate, which is conducive to the elimination of smoke and dust, reduce the loss of fly ash. It can make the flue gas flow according to the required route, so as to achieve the purpose of extending the flue gas flow, improve the fullness of the airflow in the furnace, control the location of the center of combustion, prevent local slagging in the furnace. Air secondary air can also provide A part of oxygen to help its combustion. Our company has set secondary air on both sides of the boiler, and the height of the secondary air is differen. The two secondary airs are used in conjunction with each other to make the combustion more fully. In order to be able to play the effect of disturbing the furnace airflow, so as to achieve the purpose of extending the flue gas flow, improving the airflow fullness, and making the combustion more fully, Jiangsu Sifang’s corner tube boiler adopts independent secondary fan instead of connecting the secondary air from the primary air.
2. Equal velocity design Innovative design of variable cross section at the tail to increase smoke speed, reduce ash accumulation and improve heat transfer coefficient.

3. Relative stagnation zone without smoke The stagnation of flue gas aggravates the corrosion of pipes on the heating surface, while the design of Jiangsu Sifang’s corner tube boiler, there is a large inclined angle at the top of the furnace, and a large furnace arch is adopted at the furnace outlet. The flue gas flow rate through the slag condensation tube bundle is very high, and there is no flue gas stagnation area at all.

4. Design of membrane wall header without pipe joint The membrane wall header without pipe joint design and installation site membrane wall piece inserted welding can reduce the pipe butt joint and flaw detection, and shortens the installation period.

5. Dust prevention design Tail heating surface: (1) Equal flow velocity variable cross-section design of the tail heating surface to ensure that the minimum smoke velocity of the flag heating surface is more than 6m/s. (2) The tail heating surface of each stage is reserved for soot blower interface and installation of soot blower. Air preheater: (1)The smoke speed of air preheater shall be guaranteed to be 10 ~ 12 m/s. (2)Using of large diameter pipes to prevent ash blockage.

6. Low oxygen combustion Our corner tube boiler has a fully enclosed membrane wall structure, with good sealing and small air leakage coefficient of the boiler. The boiler body adopts the latest round furnace door. The furnace door is an embedded furnace door, which is welded with the membrane wall around. It has good sealing and effectively prevents low-temperature corrosion.
